Product Description
- 30kw/50kw/100kw/200kw biogas generating set,generating equipment from biomass
Project Name: 300KW Low Speed Biomass Power Generating PlantProject Contents: By using raw materials like municipal solid waste (MSW), wood chips, crop straws, saw dust, coconut shells, rice husks, palm kernel shell, coal powder and used tire, we can get biomass through gasification process. After filtering, de-hydrating, tar-removing and other necessary treatments, the biomass will be delivered to gas tank, and finally to gas engine for power generating. And at the same time, CHP System (heat collect boiler) can make heat recovery from exhaust gas to get hot water or steam, which can realize comprehensive and high-efficiency utilization of the power plant.- TECHNICAL FEATURES OF POWER BIOMASS ENGINES
-
- Unique Advantages of Power Low Speed Biomass Engines
- Power Biomass Generator Set is driven by low speed engine of 300 series, coupled with Siemens alternator, power ranging from 300kw up to 500kw. The applicable fuel can be biomass including biomass gas, wood gas, Straw Gas and coal gas etc. Our biomass engines can work at reliable performance, easy for maintenance and much longer life-span Our generators enjoy hot markets in overseas markets including Italy, Russia, Ukraine, Latvia, Croatia, Serbia, South Africa, Tanzania, Philippines, Thailand, Indonesia, Korea and Japan etc.
- Based on Biomass as fuel, the reasons why we suggest our 300 series low speed engines.
Biomass is far different with methane base gas (natural gas, biogas and Coal mine gas etc). Biomass is much more tricky, it is low in heat value, high in tar content and unstable in gas quality (TAR always raise problems of pipeline-blocking, cylinder-pollution and spark plug-jamming etc). So, there are few engines can be fired by biomass properly. However, our 300 series low speed engines can work at biomass smoothly. The key reasons are that our 300 series engines have unique and remarkable features & advantages as follows: - Cylinders Structure in Line & Upright and Concise Layout, which means easy and low cost in maintenance;
- Large cylinder (Bore × Stroke=300 × 380mm), Long Stroke, Low Speed and Big displacement 215L, which means big reserve power capacity and constant power output.
- Low Engine Speed at 500 or 600RPM, which means high reliability for continuous operation, sufficient combustion, low exhaust gas temperature and high heat efficiency; Low Engine Speed can reduce dramatically wearing of engine parts, prolong life span.
- Naturally Aspirated (no turbocharger and Intercooler), which means low failure rate and minimal downtime (Tar in biomass always block and damage turbocharger and intercooler);
-
- Internal Mixing System (for high hydrogen gas). Gas and air intake separately, then mixed in combustion room, which means no risk of backfire and knocking.
- Strong Treatment and Resistance Ability against TAR, which means long term trouble free operation.
- Low Noise, low engine speed means lower noise, the noise level ≤ 100dB in working condition. By using silencer, the noise level can be ≤ 80dB.
- CHP System (Combined Heat and Power), making heat recovery from exhaust gas to get hot water or steam, which can realize comprehensive and high-efficiency utilization of the power plant.
- Long Overhaul Time of 60000 hours and lifecycle of 20-25 years, which secure constant economic benefits of your power plant.

- Requirements for lubrication oil and cooling water:
- The biomass genset is equipped with complete lubrication oil system. Lubrication oil consumption is less than 1.0 g/kW.h; Lubrication oil specification: 40CD or 15W40CD (GB/T11123-1989) or SAE40;
Engine's high & low temperature cycle adopts softened water. Cooling water should be clean water with slightly alkaline, shall not contain corrosive substances, such as chloride, sulfate, or acid, etc. Detailed requirements are as follows:
Total Hardness (CaCO3) ≤100ppm; Chloride-ion Content<150mg/L; PH Value 7~8.5
- Biomass Quality Requirements
-
- Before entering into engine, the biomass should be appropriate filtering, gas-liquid separation and pressure regulation. If the temperature is too high, it should be through cooling treatment, and make sure there is no liquid content in the gas.
- Gas temperature≤40°C, Gas pressure 2.5~10kpa, Pressure change rate≤1kPa/min, Tar content≤20mg/Nm3,
- H2S content≤50mg/Nm3, Impurities particle size≤5μm, Moisture content≤20 mg/Nm3, Impurity content≤30mg/Nm3, Heat value≥4MJ/Nm3.
- Ambient Environment requirement
- The genset can run steadily and continuously at following environmental conditions: ambient temperature: -20°C~+40°C, relative humidity<90% (20°C), height above sea level≤2500m.
In standard conditions (atmospheric pressure 100kPa, environment temperature: 25°C, air relative humidity 30%), the genset can work at full load of output power 300kW.
- Brief introduction of genset main system
-
- Gas system
- The gas system is the equipments from biomass-storage tank to biomass engine, like air intake duct, pipe, valve, flame arrester, control equipment etc.
Clean biomass are delivered from biomass-storage tank to biomass main pipe, and then to branch pipe, butterfly valve, and finally biomass engine. For the purpose to ensure safe running of biomass genset, butterfly valves, emergency shut-off solenoid valve, dry-type fire arrestor are installed in biomass transmission pipeline.
Following is biomass transmission route: biomass storage tank→main pipe→fire arrestor→butterfly valves→branch pipe→butterfly valves→biomass engine. In some projects, in order to fully guarantee the cleanness of biomass, basket-type filter will be installed. - Exhaust system
- The exhaust system includes bellows expansion joint, exhaust pipe, muffler and muffler support. If with CHP or waste heat recovery system, for the purpose to avoid damage to muffler and heat recovery system by high exhaust pressure, explosion-proof valve will be installed on the exhaust pipe.
Following is the working order of the exhaust system: Gas generator set exhaust vent →expansion joint→ pipeline→explosion-proof valve (optional)→ CHP/waste heat recovery unit (optional) → pipe→ muffler → the air atmosphere.
Engine exhaust temperature is about 550°C, so the exhaust system components are made by high-temperature-resistant material. The exhaust pipe is hanged on the roof by hoop with hoisting wire rope and the muffler is installed on the muffler bracket.
The exhaust pipe sizes is DN300, and the engine exhaust pipe in the generator room shall be wrapped with two layers' insulations: the inner layer by aluminum silicate ceramic tube shell with thickness at 50mm, and the outer layer by galvanized iron with thickness at 0.4mm. After insulation, the surface temperature should not be over 60°C.
- Cooling System
- Regarding to cooling methods, gas engine is with open cooling as standard (closed water cooling of radiator is optional). In order to improve the corrosion-resistance performance of cylinder block and cylinder jacket, increase thermal efficiency, the engine cylinder and cylinder-head exhaust-pipes are cooled by fresh water. Lubrication oil cooler and fresh water coolers are cooled by water from cooling tower.
High temperature cycle (called inner cycle) is mainly to cool parts like the cylinder block, cylinder jacket, cylinder head, etc. Low temperature cycle (called outer cycle) is mainly through heat-exchanger to cool the lubrication oil and cooling water in the high temperature cycle; the water in the low temperature cycle is cooled by cooling tower, its water temperature is about 20-30°C. Cooling water for low temperature cycle is 40m3/h, through the heat changer; temperature is increased by 15°C. The inner cycle used softened water; the consumption rate for one genset is about 5kg per day.
As shown in the following drawing, low temperature water flow-line: cooling tower→fresh water pump→lub.oil cooler→fresh water cooler→cooling tower.
High temperature flow-line: fresh water pump→water inlet manifold→gas engine→heat-resistant water chamber of exhaust pipelines→fresh water cooler→fresh water pump.
